我这其实只是实验和搬运，还是感谢伟大的walkline群主，他弄好的，我只是负责搬运发布给新手看。
之前一大堆人问我配网的事儿，输入下wifi名称密码这么麻烦吗，好吧，有求必应，之前的配网是通过ap模式建立热点来搞定的，确实不够优雅，现在智能配网他来了！

首先纯mpy解决不了，别想了，因为mpy的network不支持混合模式，无法解析网络数据，门都给你焊死了！
所以要自己打固件，方便顾及小白，我直接上代码了：
改动地方有两处：
1 ports/esp32/main/CMakeLists.txt
${PROJECT_DIR}/machine_sdcard.c
下面一行大约84行左右
插入一行新的

${PROJECT_DIR}/smartconfig.c

2 新建 ports/esp32/smartconfig.c
内容为

完事儿了，make吧
make好了之后就可以import smartconfig了，测试py在此：

from utime import sleep
import network
import socket
import smartconfigdef inet_pton(ip_str:str):'''convert ip address from string to bytes'''ip_bytes = b''ip_segs = ip_str.split('.')for seg in ip_segs:ip_bytes += int(seg).to_bytes(1, 'little')return ip_bytesdef send_ack(local_ip, local_mac):'''sent ack_done event to phone'''udp = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)udp.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)data = smartconfig.info()[3].to_bytes(1, 'little') + local_macport = 10000 # airkiss portif smartconfig.info()[2] == smartconfig.TYPE_ESPTOUCH:data += inet_pton(local_ip)port = 18266 # esptouch portprint(
f"""- sending ack:type: {'esptouch' if smartconfig.info()[2] == smartconfig.TYPE_ESPTOUCH else 'airkiss'}port: {port}data: {data}length: {len(data)}
""")for _ in range(20):sleep(0.1)try:udp.sendto(data, ('255.255.255.255', port))except OSError:passprint('- ack was sent')station = network.WLAN(network.STA_IF)
station.active(True)print('- start smartconfig...')
smartconfig.start()print('- waiting for success...')
while not smartconfig.success():sleep(0.5)print('- got smartconfig info')
ssid, password, sc_type, token = smartconfig.info()
print(smartconfig.info())print('- connecting to wifi...')
station.connect(ssid, password)while not station.isconnected():sleep(0.5)
print('- wifi connected')while station.ifconfig()[0] == '0.0.0.0':sleep(0.5)
print('- got ip')
print(station.ifconfig())send_ack(station.ifconfig()[0], station.config('mac'))

运行后提示等待配网，这时打开微信——小程序——搜airkiss配网有个esp模组airkiss配网那个，或者关注乐鑫公众号——产品资源——airkiss设备
配网吧然后会发现esp32 自动获取wifi密码并连接了
